C.,acorl'iorationofDelattvare` appliationNotember 2o, 1940, serialNacesfiss icfoiaims: (ci. 12o-29) This invention relates to copy holders`and more particularly to devices of that..Characterv in whch`succeeding lines of written text material are successively designated`in `a step-bym-step manner.

Inthe art to which this invention v`appertains L there are,generallyspeakingitwo types of construction; one inwhichfthe materialtobecopied is bodily moved under the control ofv ant-operator to presentsucceeding lines thereof tow a stationary line designating guide, andanother in which a designating means is shifted withv respect to copyheld in a stationary position. Y This invention is primarily directed toimprovement of the nrstr mentioned type of construction although certainfeatures thereof are Yof wide adaptability toall types of copyholdingapparatus.

Although co'py holdersare subject to a variety of uses in a number ofoperations incident tothe preparation of written textmateriahthe mostextensive commercial "application 1' ofv these Adevices f is inconjunction VwithV `the ordinary typewriter and as an adjunct to typesetting machinery. t Inv either case, the copyist is1 continuallyconfronted with succeeding sheetsof copy material of varyingcharacteristics. Of these; the important differences: encountered areusually in the' sizeof the paper-von-which the material to be copied iswritteny and in the spacing betwe'en adjacent lines of teXt material.VAs a consequence of this, sucecssive` copying operations may involvesubstantial changes in the requirements of the copy holder employed,bot/1'1"` from` the standpoint ofsize ofcopy to be supported,Y and asVregards spacing between` adjacent Writf te'n lilies. s f

In an'` eiort to render copy holders susceptible to adjustment toaccommodate a Widelvariety ofv copy' material', it is now the practicetol associate some adjustable limitingin'eans with.. the

for efffectingthe adjustments mentioned above are successful insofarvasthe accuracy of the adjustment is concerned, the means for eectingadjustment is such thatmanipulation thereof` to" secure the desiredadjustment isa time'con- Santing operation which, to' alargeextentdefeats the very purpose of the copy holderiitself,

namely: increased speed in the preparation of copied written matter withimprovement `of accuracy; Other" known devices for" adjusting 7copyholdersgso that; the relative movement between the lineY designatingguide and the copy` itself mayicorres'pondfto a wide variety of linespacings, i

arev susceptible tov quick andeasy operation but 60' are of' suchconstructionl that vibration of the copy` holding apparatus incidentbtoits normal use Will impair the accuracy of the adjustment. In someycases, these quick adjusting means are not only notr'esistant tovibration but' also do not provide' for an? accurate adjustment in therst instance. l

Another problem encountered in conjunction with the commercial use ofcopy holders is that most of the apparatus now in use will accommodateonly copy of a Width either equal to `or less than the width of the copysupporting panel. Thus, if it is necessary to copy from asheet or sheetsof printed matter which` are wider than the supporting panel ofthe copyholder, those margins of the sheet extending, beyond the copy lholderare unsupported. The result of this is that the unsupported portions ofthe copy are never subjected to an initial alignment and are subject todistortion by Aair currents and as a result off curling normal t'o paperof slight `thiol:- ness.` Of course; misalignment of any portion ofthecopy will vrender inaccurate the designations of the line guide, therebyincreasing the likelihood of the occurrence of errors andreducing theefciency of the copy holder to such an extent that its use' for widecopy is hardly lfeasible. n L. l -v A'iew attempts have been made toprovide for the supportotcopy wider than the supportingfpanel of thecopy holding device. These attempts have been characterized by failureto-.pro-l vide apparatus whereby rapidand accurate location of thepaper.` isA possible consistent with ilrm support during. any i norma-lcopying operation. f n s It is thereforey an objectot this invention to`overcome all of the foregoing disadvantages and Ato provide` a copyholder which is adjustable to accommodate sheets-of copy of a widevariety of sizes and which may. be adjusted to permit stepby-stepdesignation of lines spaced apart any distance within the normal rangeof handwritten, typewritten or printed matter. t

According to this invention, it is contemplated that 4sheets of'` copywider than the copy supporting panel may` be accurately aligned `and`rmlyflield in aposition.` to permit clear designation bya lineguide,While the adjustment of thenrelative movement between the copysupporting panel andthe line guide may be quickly `and easily.effctedand is substantially resistant to displacement by vibration. j s

It is a further object of this invention to provide a copy holder whichis quiet in operation, may be 'readily transportedV from place Ato placeand .is quickly and easily assembled and repairedf s Other" objects andadvantages 4of this invention will beapparent from aconsiderationlofFigure 1 isa View in front elevation of a copy holder constructedaccording to this invention,

Referring infgreater detail to the drawings, and

'particularly to Figures 1to 4 thereof, the copy holder shownconsists-of a baseA I0, a vertical standard-or guide I I attachedthereto, anda-copy supporting member I2 slidably mounted for telescopingmovement on standard VI I. y Y

Base I0 includes a flatportion adapted to contact a desk, table or thelike and a vertical tongue I3 to which standard II isaxed. It will benoted that the flat portion of base IIJ extends for i a considerableldistance on either'side of tongue I3 to insure the maintenance of thedevice in vertical position under all normal operating conditionswithout the necessity for fastening to any permanent resting place." Itwill be understood that this construction enhances the utility of thedevice as a whole, ready portability being a highly desirablecharacteristic since a single copy holder Vmay be used at differenttimes and in different locations by several stenographers.

Standard Il consists of a rear plate I4, guides l5 along the oppositevertical `edges thereof, a

bottom plate I5and a top plate Ia. Bottom plate I6 rests on a portion ofthe flat upper surfacev of base I0 forward of tongue I3 to which rearplate I4 is affixed at I'I.

Copy supporting member I2gconsists of afront plate. I8 slightly widerthan'plate I4 of. standard Il, provided with guides I9 along 'itsvertical `porting member I2 and serves to hold sheets of paper or othercopy thereon. This device comprises primarily a ila-t bar 2l extendingfor the `full width of front plate I8 of copy support I?.

and a pair of L-shaped hat strips 22, one shank v of which extendsupwardly from either end of flat bar ZI, while the other shank extendsrearwardly across the top -20 of supporting member I2 in a plane atright angles to the plane of bar 2I. Strips 22, at their endsl remotefrom bar 2l, are connected"` by a'barrel 23 which includes twodownwardly projecting tabs 2t. Eachtab 2li is attached to a leaf spring25 which in turn is attached at 26 to the rear face of plate I8. Springs25 are soadjusted ythat they normally tend to hold bar 2I against thefront face of plate I8. It will'be readily understood that inconstru-cting the copy gripper device bar 2l, strips 22, barrel 23 andtabs 2E; may be stamped from a single blank and may thereafter be bentinto the form shown in Figure 3. The flat surface of bar 2I which facesthe front of plate I8 is provided with a continuous strip of resilientgripping material 2 which conveniently may be made of sponge rubber. Athumb rest 28 is attached to the center of top Vwall 29 of member I2.

In the construction shown in. Figure 2, barrel 23 has detachablyreceived therein one arm of a U-bar 29. U-bar 29 is mounted for pivotalmovement about barrel 23 as an axis, the free arm thereofextendingrearwardly of plate I4 of standard II. f e

When copy is to lbe held on supporting member I2 in reading position,the operator may grasp barrel 23 andthumb grip 28 with this fingers andpress them toward one another. This will result in'compression ofsprings 25 and the forward movement of strips 22 andb'ar 2l carriedoientlyto accommodate a sheetor sheets of copy therebetween, such copyis inserted and an edge thereof is pushed up until it comes to restagainst the lower surface of the shanks of strips 22 which are at right,angles to the'long axis of the plate I8 and hence to the paper heldthereagainst. Thesefshanks of strips 22 serve to align the paper on thesupporting member I2 for the reason that they lie in a plane parallel toits top 2t. Once the paper is in position, thumb grip 23 and barrel 23are released. Springs 25 then moveto normal position (as shownin Figure3) thereby compressing the sheet or'sheets of copy between grippingstrip 21 and the front face vof plate I8. Since gripping strip 2l iscontinuous for the full length of bar 2l, the copy will be held rmly inaligned position during the ordinary manipulation of the copy holder.

If material is to be copied from a sheet of a boundV volume,v suchl asVa stenographers notebook, the top vedge of bar 2lv is used as a sightline to align the copy while pages not in use may be thrown back overtop 2l) and held against back plate I4 of standard II by the free arm ofU-inember 29. Since U-member 29 is mounted for pivotal movement inbarrel 23, the distance of the free arm thereof rfrom plate I4 maybeadjusted to accommodate any Dumber of sheets uP "to"4 a "cumulativethickness equal to the lengthV of theradialarm of theflJ--rnemben` l Y,{Sincethematerial-tofbe copiedfis'held between 'gripping strip; 2l'andthe front plate Iifo'frthe V `cop ysupporting member; it will hangdownwardly 'paralleltothe front @face of plate I8; Inl order'tof-designate a particular line tobe read; a line designatingguide'vSD; shownonlyjin Figure 2,is )ordinarilyemployed Guide 30isfmounted toex- ,p Y

Shelf "4l has Va vertical portion 50 Whichis welded orlfothferwise' suitably attached to `plate I4, while i verticalsportionis5I of shelf 43 are of similarcon struction and function. l

Inorder to accelerate the 30- return of lifting bar 354 to startingposition, a spring 54. is `attached to shank'46 thereof and extendsbetween-a portion of .said shank and a portion of shelf 41;@ 'When it'isdesired to vrestore i the copy support IZ'to its' original fullyretracted `3.5- position` asshown in Figure 3 from an extended positionsuchasV that shown in broken lines in ligure` I, operating lever 34 ismoved in a direction opposite to the arrow shown in Figure 3. Thismovement'willr result in the compression of 40 a leaf spring 55. whichis attached at one end to base plate I6 of standard I`Iy the freeendunderlying shank of `liftingloar 'and normally serving tolimitthei'downward movement thereof.' Upon compression tif-spring 55, shank45 45 will move downwardly thus causing pivotally attached cramping bar36 to move downwardly andto strike the ends ofthe fork 52 yof thecramping bar 3l. cramping bar 3l isthuscaused to -imov'etoapcsitionatright angles to the axis of rodi 38rby-1novement about point53 as a fulcrum.

IZtotheposition shown in Figure 3 -fromthefposition shown" in the broken linesin Figure lj'wouldnormally be quite rapid and noisy. i According torthisinvention means are provided to cushionthe fall of copysupport l2. sT'Referringfagain-to-Figure 9, it will be seen that rod 38 is providedwith a threaded end 56 which is passe-d through a small aperture in `thetop p plate 20 of copy support i2. A nut 5! serves to maintain theconnection. Located on the` underside Vof top 2h there is a cylindricalsleeve 58 which may be constructed of rubber or other resilientmaterial. Sleeve 58` serves to space top 2l) ofcoly support I2 from topplate Ia of standard I I when support Iltis in fully retracted position.A Siriceiod 38'isattached to top 20 of copy support I`2'i't'is evidentthat the rod and copy sup- Thus, rod `33 `will no 4port will movetogether as a unit with respect to standard II-. Copy support I2 isguided in its movement with respect to` standard jII by the overlappingengagement of members I5 land I9. The guiding of rod 38, however, isaccomplished by employment of bearings 4I and 49 and acylinder 59 whichis supported from standard II. As will be seenupon further reference toFigure 9,

.and to Figure l0, cylinder 59 is open at' one end while the other endis closed and has extending axially therefrom a pin 60 of rectangularcrosssection. In the cylindrical wall of cylinder 59 nearthe closed endof the cylinder-an air escape aperture 6I is provided. The cylinder isarranged to rest against the underside of shelf 49 and to be resilientlyheld in that position. To this .end a leaf spring 62 extends from bottomplate I6 of standard II to which one end of it is attached. The otherend of spring 62 is provided with a rectangular aperture yfor thereception of f pin 69 on the closed end of cylinder 59, the thrust ofspring 62 being of a character to urge cylinder 59 upwardly against thelower surface of shelf 49; VRod 38 may be inserted into the free end ofcylinder 59 through the bearing apertures 4I and 49a in shelves Ilia and49 respectively. The bearing apertures are of a size sufficient toclosely surround and act as a guide for rod 33. On the other hand,cylinder 59 is of an internal diameter somewhat in excess of thediameters'of the apertures of bearings 4I and 49a and the'diameter ofvrod 38. Thus, the free end of cylinder 59 may rest around the deningedges of the bearing aperture v 49ain shelf 49 in such a way that thelong axis of. the cylinder coincides with the axis of rod 39.

A washer 63, functioning as a piston, is attached to the free end of rod38 by a screw-64 as well as Van annular metal washer 63a. 'It will benoted that washers 63 and 63a are of va diameter in excess of thediameter of rod 38 but of a size to be y closely received for slidingmovement within cylinder 59.? Each of the washers has a separatefunction. When copy support I2 is being moved upwardly in response tothe operation of lever 34,

vthe upper Washer 63a, will eventually strikef'l vagainst the thickenedportion of the shelf 49 which serves 'as la bearing for rod y39. Thiswill prevent copy support I2 and standard II from becoming completelydisengaged since the diameter ofwasher 63a is too great to permit of thepassage thereofthrough the aperture in shelf 49.

On the other hand, when operating lever 34 is moved in a directionopposite to the direction of the arrow of Figure 3 thereby adjusting thel'cramping bars so thatl copy support I2 may fall by gravity to theposition shown in Figure 3, piston V63 will compress the air in thelower part of cylinderv59 as copy support I2 descends.; The escapeof airfrom' the lower portion of the cylinder is, of course, restricted by thesize of apertion, as shown in the broken lines of Figure 1.y

At this time, the upper edge of washer 63a will rest against the lowersurface of shelf 49; thereupon cylinder 59 may be grasped by the hand of(the operator and moved in the direction of the `ure 7) may pass.

farrow in Figure 9. This will result inv compression of spring 62 andsufcient downward movement of cylinder 59 to permit the freeend thereoftoA lie below the lower edges of washer63. When this condition exists,the free end of cylinder 59 may be swung out of axial alignmentwithshaft 38 and its piston 63, whereupon the entire cylinder may be removedfrom the machine by simply lifting pin 50 out of the aperture in leafspring 62. This permits ready access to screw 64 which holdsY piston 63in position. As a consequence, piston E3 may be readily replaced. Whencylinder 59 is again restored to normal position, pin 69 is passedthrough the aperture in springBZ. The leaf spring is then fullycompressed and the free end of cylinder 59 is passed into axialalignment with rod 38, thereupon the cylinder is released thuspermitting spring 62 to force the saine upwardly so that its free endabuts the lower surface of shelf 49 in the manner shown in Figure 9.

As has been stated before, the extent of movement of copy support I2upon depression of operating lever 34 depends upon the amplitude ofmovement of lifting bar 35 which, ofcourse, controls the extent of liftimparted to cramping bar 39. Since lifting bar 35 is under'the controlof the operating lever, it is evident that adjustment of amplitude ofmovement of tongue 33 will deterrnine the amount of ymovement of copysupport I2. It is evident that it is desirable that lines of materialbeing copied be presented in succession for reading above linedesignating guide 30, and since various types of printing, typewritingand handwriting involve lines spaced apart for different distances, itis highlydesirable that convenient means be provided for controlling theamount of movement of copy support I2 upon any single depression oflever 34. In other words,

each depression of lever 34 shouldbring the next succeeding line intoview just above copy designating guide 39. To facilitate the adjustmentof the amplitude of movement of lever 34 to control the movement of copysupport I2 so that successive lines of substantially anytype ofprinting, typewriting or the like may be brought into view, a limitinglever 65and a micrometer screw 66 are vmounted on and move withoperating lever 34. Upon'reference to Figure 5, it will be seen that theoperating lever 34 is generally U-shaped in cross-section andthatlever65 is pivotally attached between the two downwardly extending shanks.The pivotal attachment is effected by a screw 6l and a nut E8. Washers69 are located on either side of the levers while a spring washer lenormally urges the lever to the left as viewed in Figure 6. The top ortransverse portion of the vU shaped lever is slotted at 'II (see Figure4) for the reception of .the lever. A reentrant slot 'I2 is providedmidway of slot-1I on the side toward which lever 65 is urged by springwasher 10.

Lever 65 consists of a handle 'I3 and three members 14, 'I5 and'lG, eachpresenting a chordwise fiat edge. EachY of these edges is adapted tocooperate with and rest upon a portion of the top of a support TI, whichextends upwardly from base IIJ. Suppe-rt 'l1 is provided with -a slot at'Ila through which member 'I6 (see Figure 5) or both member 'I6 andmember 'I5 (see Fig- The flat edges of members 74, l5, and 16 of lever65 vare usually adjusted so that they will lpermit movement of lever 34vto an kextent suicient to cause movement of copy support`I2 to an extentequal to tripple, double and asaome `at 39. The adjustment of lever 65is maintained bythe action of spring washer `'lil and by "the edgesofslots 1| and" 12. In the position shown in Figurey 7, thechordwiseedge 1 4 of :lever .6.5 is .so disposed with respect tothe axisof screw 61 that, despite pressure on lever 34, handle 13 will bemaintained against oneend of slot 1l. Gn ltheother hand, when lever @5is `inthe position shown in Figure 8, handle 1,3 willbemaintainedagainst theother edge ofl slot 1|. In the intermediate position wherethe limiting 'surface is'edge 15, spring washer 10 tends to move "thelever 65 to the left causing handle 13 to be accommodated in reentrantslot 12frorn whichit oanlwmove in `neither direction. To release lever65 from theintermediate adjustment, itis necessary to move the lever tothe right as viewed in Figure 6, thereby compressing spring washer.1111.r

.Although adjustment of lever- 65 maybe effected rapidly so as toaccommodate. single.

double and` triple space typewriting, itis evident that :some types ofcopy material mayrnot 4conforrnto any standard. For this reason, a,micrometer screw tV is provided. The shank yof this screw passes through`a nut 18 attached between the shanks of handle y34. A lock nut 19serves ,to lock any adjustment lagainst displacement by vibration. Itwill beseen thatthe free end oi screw 66 can be moved tostrike against aportion of the upper surface of `support 11 on that side of slot 11a,opposite theside on which the variousedgesofmembers 14, 1 5 and16'coo-perate with a surface oisupport 11. By adjustment of micrometerscrew .6,6, it is 'possible ato produce movementyof copy support l2tomany extent between la maximum dened by the edge of member 14 and aminimum controlled entirely b-y `screw 66.

When material is being supported on plate I8 of copy support lormovement past .line `designating guide El), itis vnormally held solely-bybar 2i, the construction and operation vof which has already beendescribed. `llt will be noted that bar 2l is coextensive in width with`front-I plate !8 of copy support l2. Normally, copy support l2 will beof a width to accommodate at least ordinary paper, i. e., eight andone-half inches.

According to this invention, however, it is pos- 4- silole to supportcopy -of a width considerably excess of normal. To' this end the wideline designating guide and widecopy holder showniin Figures 1, 3 and 11to 14, inclusive, are employed. As has been stated, line designatingguide 35] is mounted on a U-shaped bar 3J, `one .shank of the U-barbeing inserted ina barrel pro.-

When lines of copy of a width inl wide line designating guide 80 ispassed thereover. "Another U-bar 8l, similar inv construction to 'U-bar3l, ih also employed. One shank of "U-'bfar :8j is placed within thebarrel -of wide line designatingguide ,80, atthe end opposite the end inwhich a shank of U-bar 3l is received, and then "the free shank thereofis inserted in barrel 32. The separate U-bars are shown in Figure 1 1,'the' separate wide line designating guide in Figure 12, while theassembled unit is shown in Figure l. During such periods as wide linedesignating guide 30 is employed, the guide 3i) may be placed vinstorage.

While it is evident upon consideration of Figure 2V that `bar 2| wouldserve 'at least toa certain' extent to'align and holdcopy on frontplatei8 of copy support 12, it is also evident that when the copy is of awidth such "that itextends considerably beyondplate i8 on either side,the edges 'of V4the copy not held byI bar 2| will not maintain theiraligned position since the paper will not be sufcientlystii 'to maintainits upper edge on a straight line. `The action of gravity as Well'as theaction oi air currentswill normally cause "the free ends of the copy tofall below the horizontal 'plane designated byV the lower edge ofthehorizontal Shanks of strips 2E-which serve "as aligning means.Toovercome this difficulty heretofore considered insuperable, a bar 82vhaving copy grippers u83 thereon -is employed. Bar '82 is `used insubstitution for `U-member l29 which is removed from barrel 23 andplaced in storage. One of the Shanks vof bar 8-2 is then inserted` inbarrel 23 until `the `end of the other shank'can be aligned and insertedin-the opening at the other end of kbarrel 2-3.- Bar 82. `is Athenaligned as shown in Figure l lby causing the forward runthereof Ato reston -top 28 of copy support` l2. Copy grippers -83 are each Aprovidedwith fa barrel r13d-so that when `the grippers are mounted on rod A32they are Afreely slidable `to accommodate copy of a width anywhere fromjust exceeding the width of plate I8 to the full width ofbar82'. It willbe noted upon reference to Figure 14 that copy grippers 83 are providedwith agmouthi35 and that surface 86 constitutes a limiting `surfacebeyond which-copy may not be inserted in the -mouth of grippers 83. TheAlimiting surface d 'is so positioned that it will -lie in the same'horizontal' plane as the limiting surface constituted by theundersurface of `that portion 1 `82 is placed in operation, copygrippers Bwmay Y .have `their mouths 85 alignedfwith the underside ofstrips `22 by merely forcing the forward run of r'od182 ldownintocontact with the upper surface of `strips 2,2. `This eliminates chance of error :since regardless -of how many times rod .132 may `loeremovedand replaced, once itis inserted in barrel 23, it is onlynecessarytoswingA bar forward to point .of contact with strips .22 toinsure alignment A of the copy grippers 33 in -such .a `way ,that :theywill Acooperate with copy grip,- per '2.2! :in aligning the same edge ofa, piece of copy. i l l i The operation of Ythe copy `holder as a whole,when -rod -82 `and grippers 83 fare attached, is similar to theoperation described in conjunction with Figure 1. In releasing thepaper, however, it is necessary to separately release the edge from eachof the grippers 83 in addition to in closed or gripping position asshown in Figure 14. The raised portion in the forward run of rod 82'isfor the purpose of permitting use of thumb rest 28, when wide copy is inthe machine. W A' Although the foregoing description has been concernedwith a preferred. embodiment of this invention,it will be understoodthat many modifications of the illustrated construction may be madewithin the' scope of the appended claims;

."Whatis claimed is:

l. `In a copy holder including, a stationary guide, a copy supportmounted thereon for telescoping movement, a piston rod attached to thecopy support, 'and means acting through said piston rod for raising andlowering said copy support, a cylinder adapted to receive a part 'ofsaid piston rod, an abutment on said guide, the Y.

end* of saidcylinder Vthrough which 'said piston rod passes restingthereagainst, resilient means interposed intermediate a part oi saidguide and the other end of said cylinder, whereby said cylinder is heldin position against said abutment and may be removed by compression ofsaid'resilient means. l

2. In a copy holder including, a stationary guide, a copy supportmounted thereon for teler scoping movement, a piston rod having one endattached to the copy support, and means acting through said piston rodfor raising and lowering said copy support, a piston detachably mountedon the end of saidrod remote from. the end attached to said copylsupport, saidpiston being `of a diameter in excess of the diameter ofthe rod, a cylinder adapted to receive said piston, an abutment on saidguide, one end of said [cylinder resting thereagainst, and a leaf springinter-posed intermediate a portion of said guide i and `the other end ofsaid cylinder, said spring normally holding said cylnder in engagementwith'said abutment, said rod passing through an aperture in vsaidabutment into said cylinder,

said piston being too large to pass through the Y.

aperture, whereby said cylinder may be removed fromoperative position bycompression of said spring thereby permitting easy replacement of saidpiston without removal of the rod.

3. In a vcopy holder including, a stationary guide, a copy supportmounted thereon for telescoping movement, a piston rod having one endsupport, said piston being of a diameter in excess of that of the rod, acylinder adapted to closely receive said piston, said cylinder being`open at'one end for the reception of the piston and having only a verysmall aperture near the other end, an abutment on said guide having anaperture therein to closely receive said rod, the

open end of said cylinder resting against that part of the abutmentdefining the aperture, and

compressible springmeans `interposed intermediatea portion of said guideand the substantially closed end of said cylinder normally frictionallyholding the open end of said cylinder in contact with said abutment,whereby the device may be assembled by passing the rod through theaperture in the abutment, attaching the piston, compressing theresilientmeans, passing the open end of the cylinder over the piston andreleasing the spring means which will then hold the cylinder inposition.

4. In a copy holder including, abase, relatively movable members carriedthereby, one of said members serving to support copy` and the otherincluding line designating means, means for moving one of said membersto bring a selected line of copy into designated position, and anoperating lever for actuating said moving means, the extent of movementof the lever determining the extent of movement of the movable member,means for selectively adjusting the extent of movement of thelever toone of three amplitudes, and separate means for selectively elfectingadjustments intermediate three amplitudes, both of said means beingcarried by said lever, whereby quick` adjustments may be made forcopying material of normal spacing while adjustments for irregularspacing may be made.

5. In a copy holder including, a base, relatively movable memberscarried thereby, one ol` said members serving to support copy and theother including line designating means, means for moving one of saidmembers to bring a selected line of copy into designated position, and

an operating lever for actuating said moving means, the extent ofmovement of the lever determining the extent of movement of the movablemember, means presenting a limiting surface underlying said lever, and asecond lever pivotally attached to the liirst lever, said second leverincluding several chordwise surfaces located at different distances fromthe lpoint oi" pivotal attachment, said second lever being movable topresent any one of said chordwise surfaces to said base, whereby thestroke of the rst named lever may be limited to an extent determinableby adjustment of said second lever.

6. In a copy holder including, a base, relatively movable memberscarried thereby, one of said members serving to support copy and theother including line designating means, means for moving one of saidmembers to bring a selected line of copy into designated position, andan operating lever for actuating said moving means, the extent ofmovement of the lever determining the extent of movement of the movablemember, means presenting a limiting surface underlying said lever, asecond lever pivotally attached to the first lever, said second leverincluding several chordwise surfaces located at different distances fromthe point of lpivotal atftachment, said second lever being movable topresent any one of said chordwise surfaces' to said base,v and resilientmeans for maintaining the surface selected in the position selectedwhereby the stroke of the first named lever may be limited to an extentdeterminable by adjustment of said second lever. l
